selected position.

The adjustable hinge for the door permits the door to be swung into horizontal position regardless of the angular position of the projection machine whereby a maximum clearance is obtained between the door and the wall of the projection room, and the latch mechanism is so constructed that it is capable of cooperating with the casing regardless of the angular position of the door with respect thereto.

This construction is particularly important in instances Where the projection machine is operated at a substantial angle to the horizontal since the door is frequently'brought into close proximity to the wall of theprojection room and would be prevented from opening to its full extent. Furthermore, in the case of a large machine having a comparatively heavy door it is a distinct advantage to adjust the hinge so that the door will open in a horizontal position in order to prevent the door from tending to shut or open due to the force of gravity,

Whilecertain novel features of the invention have been shown and described and are pointed out in the annexed claims, it will be understood that various omissions, substitutionsand changes in the forms'and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention.

What is claimed is: 1

1. In combination, a casing having a circular opening, a door for closing said opening, means for hingedly mounting said door comprising a hinge and means for peripherally adjusting said hinge with respect to said opening, comprising clamping devices carried on said hinge and extending through arcuate slots on said casing.

2. In combination, a circular casing, a door for closing said casing, a hinge for mounting said door, a bracket carrying said hinge and extending across the periphery of said casing, and means for slidably securing said bracket to the back of said casing whereby the angular position of said 'door may be'varied.

3. In combination, a circular casing having a back provided with a peripheral channel, a door for closing said casing, a hinge for mounting said door, a bracket carrying said hinge and exthrough arcuate slots in said casing and adapted to permitd'otary movement of said frame and to clamp said frame to said casing in any 5. In combination, a casing, a door therefor, a supporting frame, a hinge for said door commont comprising saidhinge, and latch means carr prising cooperating hinge lugs carried by said door and said frame respectively and held in aligned. position by a rod extending therethrough, said frame extending across the periphery of said casing and having an inturned flange engaging a portion of the back of said casing and means for clamping said flange to said back portion comprising bolts extending through a peripheral groove in said back portion and into said flange, said bolts having heads engaging a peripheral channel formedinternally of said back portion and being adapted to clamp said flange thereto.

6. In combination, a circular casing, a door for closing said casing and a hinge for said door comprising a frame slidably mounted for movement' about the] periphery of said casing and spaced therefrom, means for clamping said frame in a selected position and means for maintaining frame in correct position with respect to said casing during peripheral movernembers carried by said frame andadapted to engage the periphery of said casing. l
